在 COBOL 中写入顺序数据集使其成为不可访问的二进制文件

Question

以下代码应通过 DDINPUT 将一个顺序数据集作为输入，描述银行账户，并通过 DDOUTPUT 输出一个顺序数据集，其中包含余额大于 8,500,000 美元的银行账户所有者的姓名。但是，正如我们在 Stack Overflow 中，它没有。

              NOT AT END PERFORM WRITE-RECORD

              MOVE SPACES TO PRINT-ACC 
              MOVE WS-LAST-NAME    TO LAST-NAME-O

              DISPLAY "Writing " FIRST-NAME-O " " LAST-NAME-O "..."
              WRITE PRINT-ACC
              END-IF.

代码正确余额大于 8,500,000 美元的所有者的姓名但没有正确编写，因为，当输出访问数据集，VS Code 抛出以下错误：

cannot open file:zowe_path. Detail: File seems to be binary and cannot be opened as text.

我是 COBOL 的新手，我不知道在写入输出时我做错了什么。可能是 JCL 导致了问题：

//TOPACJCL  JOB 1,NOTIFY=&SYSUID
//***************************************************/
//COBRUN  EXEC IGYWCL
//COBOL.SYSIN  DD DSN=&SYSUID..SOURCE(TOPACCTS),DISP=SHR
//LKED.SYSLMOD DD DSN=&SYSUID..LOAD(TOPACCTS),DISP=SHR
//***************************************************/
// IF RC = 0 THEN
//***************************************************/
//RUN     EXEC PGM=TOPACCTS
//STEPLIB   DD DSN=&SYSUID..LOAD,DISP=SHR
//DDINPUT   DD DSN=MY.DATA(INPUTD),DISP=SHR
//DDOUTPUT  DD DSN=MY.DATA(OUTPUTD),DISP=SHR
//SYSOUT    DD SYSOUT=*,OUTLIM=15000
//CEEDUMP   DD DUMMY
//SYSUDUMP  DD DUMMY
//***************************************************/
// ELSE
// ENDIF

希望你能帮助我，因为过去几个小时我一直在努力解决这个问题。提前致谢！

编辑 #1：添加了“MOVE SPACES TO PRINT-ACC”，仍然不起作用。

尝试在更新之前将空格移动到输出记录

 WRITE-RECORD.
           COMPUTE RES = FUNCTION NUMVAL-C (ACCT-BALANCE).
           IF RES > 8500000
              DISPLAY "Adding " WS-FIRST-NAME " " WS-LAST-NAME "..."

              Move space           to PRINT-ACC

              MOVE WS-LAST-NAME    TO LAST-NAME-O
              MOVE WS-FIRST-NAME   TO FIRST-NAME-O
              DISPLAY "Writing " FIRST-NAME-O " " LAST-NAME-O "..."
              WRITE PRINT-ACC
              END-IF.

基本上你只更新 LAST-NAME-O 和 FIRST-NAME-O 记录的其余部分将是 hex-zero's 因此被识别为二进制。您将能够在主机上使用 ISPF edit 或 File-Aid 等编辑文件
